IMPROVEMENT IN DIES FOR COMPRESSING THE HEELS 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 1 80,030, dated July18, 1876; application filed June 10, 1874.

To all whom it may concern:

Be it known that I, GEORGE HOUGHTON, of Hudson, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Dies for Cornpressing Heels, of which thefollowing is a specification:

My invention consists in forming a corrugated die for compressing heelsof boots and shoes.

The object of the corrugations is that the heel may be pressed by asingle act of pressure. In doing this I am enabled to produce a heelhaving its periphery upset so as to close the joints between the liftsin the same manner as was formerly effected by the worknians blows onthe edge of the heel with the peen of his hammer. I V

Figure 1 is a plan of the die, showing its corrugations. Fig. 2 is avertical section of the die; also showing the rubber elastic pieces atthe bottom and the concaved base-piece at the bottom of the die formingthe top of the heel, the follower also being shown. Fig. 3 is a plan andsection of the base-piece.

The die is formed of steel, as shown in the drawings, and hascorrugations b I) b b, and is provided with elastic pieces 0 and D, Fig.2, and a metallic base-piece, B, which is made concave on its uppersurface, as shown at X Y, Fig. 3, so that the heel in being pressed willbe made convex and in this condition applied to the shoe. The object ofconvexing the top surface of the heel is to provide for thedepressingeffect of fastening the heel to the shoe or boot, as in practice it isfound that if the top of the heel is made flat the action of fasteningit on will cause it to become concave, and thus require much more sandpapering to reduce it to an even surface. My method-that is, making itconvexprovides the heel with a convex surface, which, in the process offastening on, becomes depressed to a level, and hence the surfacerequires but little sandpapering to prepare the same for the finish. Thebase-piece B, Fig. 3, may have a designating-number, as shown (2), Fig.3, sunk into its surface. H, Fig. 2, is a follower, which leaves theunder side of the heel concaved to fit the sole. The pieces 0 and D,Fig. 2, are of rubber, and serve to spring the heel out of the die whenthe follower H is withdrawn.

I claim as my invention- The heel-die A, provided with corrugations b12, substantially as described, and for the purpose set forth.
